Type a number in any THREE input boxes. Then click COMPUTE to solve for the fourth variable.
Angle of incidence (
Incident index of refraction (
Angle of refraction (
r ) -- set to 90 to find critical angle
Refractive index of refraction (
Speed of light calculations:
m/s = Vi (speed of light in incident medium)
m/s = Vr (speed of light in refractive medium)

Celcius to Fahrenheit and vice versa
Insert a number in either input field, and the number will be converted into either Celsius or Fahrenheit.
Note that the
method is used, so that the result will be returned as a whole number.
Blood Glucose Units: mmol/L (the standard in some countries, e.g. the UK) to mg/dL (the standard in other countries, e.g. the USA).
Insert a number in either input field, and the number will be converted into either mmol/L or mg/dL.
(1 mmol/L of glucose = 18 mg/dL)
